%% lists all exog variables

% 1
r = 0.1; % baseline interest rate: applicable to all agents except for investors selling
% 2
d_r = 0.05; % extra for investors selling: they value lower time on market
% 3
beta = 0; % end-user flow value: searches for a positive NPV house
% 4
d_beta = -.5; % difference of flow value for developers, investors in holding and selling phases -> reflects the opportunity cost of empty building
% 5
x = 100; % average NPV of a house for end-user
% 6
eps = 0; % starting value of housing homogeneity (eps = 0 - complete homogeneity, eps \uparrow - less homogeneity)
% 7
lambda = 1; % rate of departure of holding investors into impatient sellers
% 8
tau = .2; % rate of departure of end-users occupying a house = inflow of end-users searching, \tau < \lambda, because end-users stay in the house long-term
% 9
di = -2; % flow value premium for investors searching: reflects the opportunity cost of "nominal asset"
% 10
DD = .25; % mass of developers =  ratio to the total number of end-users (searching and occupying a house, normalized to 1)
% 11
II = 0.25; % mass of investors = ratio to the total number of end-users
% 12
a = 0.25; % developer cost function - level parameter
% 13
b = 0.007; % developer cost function - slope parameter
